	//
	//    * DeliveryPolicy – The policy that defines how Amazon SNS retries failed
	//    deliveries to HTTP/S endpoints.
	//
	//    * FilterPolicy – The simple JSON object that lets your subscriber receive
	//    only a subset of messages, rather than receiving every message published
	//    to the topic.
	//
	//    * RawMessageDelivery – When set to true, enables raw message delivery
	//    to Amazon SQS or HTTP/S endpoints. This eliminates the need for the endpoints
	//    to process JSON formatting, which is otherwise created for Amazon SNS
	//    metadata.
	//
	//    * RedrivePolicy – When specified, sends undeliverable messages to the
	//    specified Amazon SQS dead-letter queue. Messages that can't be delivered
	//    due to client errors (for example, when the subscribed endpoint is unreachable)
	//    or server errors (for example, when the service that powers the subscribed
	//    endpoint becomes unavailable) are held in the dead-letter queue for further
	//    analysis or reprocessing.
	//
	// AttributeName is a required field
	AttributeName *string `type:"string" required:"true"`

	// The new value for the attribute in JSON format.
